.clutch member mounted upon a rotating shaft the longitudinal thrust necessary for setting the clutch, and various forms of mechanism have been employed on or in the rotating shaft for communicating the thrust of the said screw or shifting-lever to the clutch member. Some of these mechanisms were non-self-locking, it being necessary to continue the pressure of the screw or shiftinglever for'the purpose of holding the clutch in set position. Such a device had the advantage of variability of clutching pressure combined with the disadvantages of non-self-locking, loss of power, and development of heat at the point where the clutch-setting power was communicated between the non-rotating and rotating parts. Other of these mechanisms embodied a positive self-locking at the passing of a point or center, so that when the clutch was set the pressure of the screw or lever might be discontinued without permitting the clutch to unset itself; but combined with this self-locking'advantage this mechanism contained the disadvantage of non-variability of pressure during operation when set and locked. In other words, as soon as the clutch was set and locked the operator was powerless to increase the pressure of the clutch member during operation by the further movement of the screw or shifting-lever.

One part of my present invention is to combine in one construction the advantages above referred to without the disadvantages. This I accomplish by a mechanism possessing the capacity of substantial self-locking in a plurality of positions, so that it is within the power of the operator of the screw or shifting-lever to move the clutch member through a wide range of pressures at any of which the rotating clutch-setting mechanism will substantially self-lock, so that the operator has it within his power by the movement of the screw or shifting-lever to produce any desired degree of pressure between the clutch members, and at the same time to permit the clutch to run at any of said degrees of pressure without continuing the full force of the thrust of the screw or hand-lever against the rotating mechanism. In carrying out this part of my invention I employ between the shifting-lever or screw and clutch member what may properly be termed a friction locking device or mechanism, or, in other words, one in which the lock is produced by the substantial preponderance of friction between the parts over the resultant of force tending to move said parts backward, so that the friction between the surfaces at any point throughout a range of movement is sufficient to substantially lock the surfaces against such backward movement as would permit the clutch to unset itself. I do not, however, limit myself to said friction-lock feature,other features of my invention being set forth in the following description and claims.

In the accompanyingdrawings I have shown several forms in which my invention may be embodied, butvariations thereof are of course possible without departing from the principles of my invention.

Figure 1 is a rope-drum mechanism, partly in section, containing my invention. Figs. 2 and 3 are longitudinal sectional details of the same, corresponding, respectively, with the unset and maximum set positions of the clutch, all degrees of friction-locked set positions being possible between said extremes. Fig. t is a cross-sectional detail on the line w a: of Fig. 2. Fig. 5 is a longitudinal sectional detail of a modification. Fig. 6 is a clutch-pulley in maximum set position and partly in section, with my invention applied. Fig. 7'

is a cross-section of the same on the line 3/ y of Fig. 6. Fig. 8 is the same, partly in longitudinal section, in unset position. Fig. 9 is a cross-section of the same on the line a a of Fig. 8. Figs. 1O, 11, 12, and 13 are detached parts of the construction shown in Figs. 6 to 9, inclusive. Fig. 1 L is a modification adapted for attachment to frictiondrums of old construction. Fig. 15 is a diagram to explain the direction of forces. Fig. 16 shows the wedge operating the toggles from the reverse direction.

In all of the figures A is a rotating shaft. B is a clutch member revolubly mounted on the shaft and containing the friction clutchsurface 6. O is a clutch member revolubly fixed on the shaft, containing the friction clutch-surface c. A relative longitudinal movement on the shaft between the clutch members B and C is permitted and the two are normally held apart by the interposed coiled spring D. E and E are abutments fixed to the shaft, between which the clutch members are mounted and which serve to relieve the bearings of the shaft from the end thrust necessary for setting the clutch. E is made longitudinally adjustable on the shaft, so that the distance between the abutments may be varied. F is the fixed bearing for the hand-operated screw G or lever G, by the movement of which the operater deter mines the setting or unsetting of the friction clutch-surfaces. H is a member carried by and rotating with the shaft, which receives the thrust of the screw G on one side of the abutment E and transmits it to, through, and beyond said abutment. H performs the correspondingfunction for the hand-lever G.

Heretofore in cases where it was possible for the operator by the continued forward movement of the screw G or lever G to produce any considerable variation of pressure between the clutching-surfaces it has been necessary after moving the clutch-surface up to the requisite pressure to hold it there by continuing the full force of pressure of the screw Gr or lever Gr against the rotating member H or H, or, in other words, by continuing the full setting pressure between relatively nonrotating and rotating surfaces. This has been the cause of loss of power and generation of such an intense heat between the relatively non-rotating and rotating surfaces as to in many instances destroy the same notwithstanding many remedies that have been attempted. The problem of overcoming this difficulty while retaining the advantages of a variable pressure between the clutchingsurfaces while in operation may be solved by the following mechanism, which I will first describe in connection with Figs. 2 and 3: On the forward end of the member H is formed or secured a wedge 1, interposed between the links 2 and 3, articulated, respectively, at 4 and 5 on a collar 6, which is carried by the shaft and rests against the abutment E. A collar 7, carried by the shaft, rests against the longitudinally-movable clutch member, as B. A link .8 forms with the link2 a toggle between the collars 6 and 7 on one side of the shaft-axis, and a link 9 forms with the link 3 a toggle on the opposite side. Projections 10 and 11 from the plates 6 and 7, clamped between the ears of each collar, serve to keep the links 8 and 9 in place. The inner edges of said plates also serve as'stops to prevent the toggles from reaching a straight or positivelylocking position. The shaft is slotted, as shown in Fig. 4:, to receive the wedge 1 and the toggles, which open inwardly toward the center of the shaft. The links 2 and 3 are provided with toes 12 and 13, the soles of which rest together in the position shown in Fig. 2, where the wedge 1 is withdrawn and the toggles are entirely open and the collars 6 and 7 are in contact and the clutch is fully unset. The heels 14 and 15 of the links 2 and 3 are rounded to ease the entrance of the wedge 1 between them. these toes and heels forms covers of the joints or knuckles between the toggle-links. A pulling connection 16 is provided between screw G and pin H. The mode of the operation may be explained by reference to the diagram of Fig. 15, wherein the wedge is shown as about half-way inserted. The reaction of the friction clutch-surfaces tending to open the toggles produces pressure by them against the wedge in the direction of the arrows. The inclined surfaces of the wedge are so nearly at right angles with the direction of this pressure, however, that the pressure is powerless to overcome the friction between the wedge and the toggles and is thus powerless to shove the wedge backward on whatever part of the wedge the toggles may rest. Therefore when the operator has shoved the wedge forward to the position, for example, shown in Fig. 15 he may reduce or relieve the pressure of the screw G or lever G and the friction of the wedge will substantially lock the parts against backward movement. If then the operator desires to increase the pressure of the clutch-surfaces, he may force the wedge farther forward, or if he wishes to decrease the same he may draw the wedge farther backward, and still at whatever degree of pressure he places the clutch-surfaces the friction of the wedge will substantially lock or assist in locking the parts against backward movement from that position. Therefore while the clutch is running the operator may change the pressure of the clutch-surfaces through a range depending only upon the length of the Wedge and still may permit the clutch to run at any point within this range of pressure with the pressure between the non-rotating part G and rotating part H reduced to any desired extent, and consequently without either undue loss of power or generation of heat between those parts. The-angle or degree of evolution of the inclined surfaces of the wedge from the axis of the shaft which I employ in practice is less than the angle of repose, which angle of repose will of course vary, depending on whether the surfaces are smooth and of high coefiicient of friction and highly lubricated or are rough or corrugated or of low coefficient of friction or unlubricated. Under certain conditions an angle as great as from ten to fifteen degrees might produce a complete friction-lock, while under others an angle as low as three degrees would be used.

In the construction shown in Figs. 6 to 13, inclusive, the collars 6 and 7 and toggles 2 8 and 3 9 are substantially the same as before, but the wedge is divided into two parts 1and 1", which rest against the outside of the shaft. The toggles when open likewise rest against The projection constitutingthe outside of the shaft. In this form of construction no recess need be formed in the shaft, which is surrounded by the collar 15, suitably recessed to admit the toggles and the wedges 1 and 1" and screw-threaded to receive the abutment E. It is prevented from backward movement along the shaft by the supplemental abutment E through openings in which the member H extends.

The construction shown in Fig. 5 resembles that shown in Figs. 2 and 3, excepting that the wedge 1 forms a swivel connection at 18 with the member H, also that the wedge and the'links 2 3 are of somewhat different form shown.

In Fig. 14 the maximum set and unset positions are shown, respectively, in full and dotted lines. B is the ordinary friction ropedrum. 20 is the ordinary cross-key extending through the shaft and resting outside of the shaft against the rope-drum and forced forward by the ordinary central pin 21. 22 is the stationary frame carrying the end bearings for shaft A. 23 is a yoke bolted to the face of the frame 21 and carrying the nut F, in which the operating-screw G is threaded. 24 is a shell or case fixed on the end of the shaft 3 and to which is adjustably screwthreaded the abutment E. 26 and 27 are two heads longitudinally movable in the case 24, the forward side of one of which abuts against the end of the pin 21 and the backward side vof the other of which abuts against the abutment E. Interposed between the heads 26 and 27 are the two toggles 28 and 29 opening inwardly toward each other and spread apart by the wedge 1, swiveled to the end of the operating-screw G, which swivel constitutes the point of contact between the non-rotating and rotating parts. In this case the angle of the wedge-surface is shown as decreasing from front to rear, for the reason that the more obtuse angle of front part of the wedge will force the clutch-surfaces toward each other till they are brought in contact, whereupon the more acute angle toward the rear of the wedge will come in play to vary the pressure of the clutch surfaces against each other through the desired range, while forming a friction-lock at any point of that range. 30 represents stops to prevent the toggles from forming a positive lock.

As to the surface productive of the frictionlock, I do not limit myself to the form of surface shown or-to the embodiment of it in a wedge or to the movement of it parallel with the axis of the shaft or in a straight line. As to the elements-z1 a, toggle or equivalent and wedge or equivalentwhich constitute the mechanism rotating with the shaft, whereby the power delivered by the prime mover G or G is multiplied, I do not limit myself to them either in number, kind, or arrangement. Nevertheless by constructing the duplex power-multiplying friction-locking mechanism of the toggle and wedge with a friction-lock interaction and placing said mechanism forward of the point where the contact occurs between the non-rotating and rotating parts exceedingly good results are accomplished, since not merely the friction-lock, but also the multiplication of power, may occur forward of said point of contact.

Some of the features, severally or in combination, referred to in one or more of the claims may be pointed our as follows: It will be observed that in each of the constructions shown the power-multiplying mechanism is retained by a holder or case. In Figs. 1 to 9 this is composed of the sectional rings 6 7 and plate 6 and 7 while in Fig. 14 it is composed of the shell 24. In each form this holder is mounted upon the outside .of the shaft, being screwed on the outside of the end of the shaft in Fig. 14 and in Figs. 1 to 9' being held around the shaft by the bolting of its sections together. In each'form shown this holder circumferentially binds together the opposite members of the two toggles. The abutment E is in all forms substantially outside the shaft. In Fig. 14 it is connected with the shaft by the holder 24, whereas in Figs. 1 to 9 the abutment is mounted directly on the outside of the shaft. In all the forms shown there is a screw-threaded adjustment between the abutment and the shaft. In all forms the power from the actuator is transmitted past the abutment by extendingthe mechanism inside the abutment. In all forms the clutch-setting mechanism is located substantially on that portion of the shaft protruding from the drum, so that it requires no special construction of drum substantially different from those heretofore used. In Figs. 1 to 5 it is located on that portion of the shaft between the drum and its bearing and in Fig. 14 on the outside of the hearing.

The oppositelydisposed power devices (which I have shown in the form of toggles) and the spread er therefor (which I have shown in the form of a wedge) are herein shown with the spreader extending across the line of the shaft in a position either within the shaft itself, as in Figs. 2, 3, 4, and 5, or opposite the end of the shaft, as in Fig. 14, the latter arrangement being also shown in my application, Serial No. 147,937, originally filed March 16, 1903. Claims are contained herein intended to cover generically combinations containing the spreader in either of said positions, while other claims are contained herein intended to cover combinations containing the spreader specifically in the position shown in said Figs. 2, 3, 4, and 5, leaving the claims for combinations containing the spreader specifically in the position shown in said Fig. 14 to said application filed March 16, 1903.
